To investigate implementation of National Institute for Health and Clinical Excellence (NICE) guidelines in mental health, focusing on the schizophrenia guideline. Data analyses centred on implementation of the guideline, as well as looking at a set of markers mapped to the NICE principles of implementation and other identified clinical prerequisites. A self-report questionnaire tool was sent to senior executives at mental health trusts containing questions linked to the markers of implementation and clinical prerequisites; responses were analysed with data from the Healthcare Commission audit of implementation of the guideline to show key relationships.
RESULTS
Information from both data-sets (senior executive data collection and the audit) showed that implementation is patchy, with pockets of good implementation. Findings indicate that higher levels of implementation are linked to corporate commitment and leadership, as well as support from commissioners.
CLINICAL IMPLICATIONS
Implementation might be improved by corporate commitment and leadership and better support from commissioners.

Data from the recent audit of implementation of the schizophrenia guideline (Healthcare Commission, 2006), carried out as part of the Healthcare Commission joint review of community mental health services, were re-analysed alongside data from the present study. The audit identified a number of key implementation markers, and gathered data to assess adherence with these: availability and use of family interventions and cognitive–behavioural therapy (CBT), provision of information and occupational needs, physical health checks, prescribing (atypical antipsychotics, depot formulations, treatment-resistant schizophrenia), monitoring, medication and advance directives. A proxy measure of guideline implementation was created within the data-set by summing the trust-level scores for each of the indicators in the audit.
Data were analysed using SPSS version 14 for Windows. Correlations and one-way analyses of variance (ANOVAs) were used to identify significant univariate relationships; linear regression was used for multivariate effects. In order to examine fully the effect of corporate commitment and leadership, a new variable was constructed comprising identified executive lead, identified clinical director lead, clinical champion, team to support the clinical champion, and reports to trust board. The new variable showed an acceptable Cronbachs µ value of 0.68.

Corporate and local leadership (mapped to NICE principle 1)
Staffing and resources (mapped to NICE principles 2 and 3)
Commissioner resourcing (mapped to NICE principle 4)
Accessibility of guidelines (mapped to NICE principle 5)
Operational implementation (mapped to NICE principle 5)
The use of outcome measures is a proxy for implementation, because it is a
precursor for appropriate recording of patient information and an indicator
that diagnosis is being recorded. Respondents were asked if clinical teams
routinely used outcome measures. Responses are shown in

respondents indicated that their trust used a computerised clinical
information system for patient details.

Inferential results
Commissioner support of health technology appraisal implementation
One-way analysis of variance showed that a lower commissioning score is
associated with:
Correlation showed that a lower score for commissioning support is linked to a lower level of commitment and leadership (see below; R=0.180, P=0.048).
Commissioner support of guideline implementation
Our hypothesis was that, as with support for health technology appraisals,
commissioning support of guideline implementation might exert an effect on
other variables. One-way ANOVA showed that poorer commissioning support of
guidelines was associated with:
NHS funding problems
Our hypothesis was that funding problems might curtail implementation. This
proved not to be the case for audit of health technology appraisals, where
reported funding problems were associated with:
Commitment and leadership
One-way ANOVA showed that better levels of commitment and leadership were
associated with:
Correlation showed that better commitment and leadership is associated with more prevalent use of outcome measures (R=0.194, P=0.008).
Commissioner support, and corporate commitment and leadership
Correlation shows a positive relationship between commissioner support for
health technology appraisals and commitment and leadership (R=0.180,
n=181, P=0.016).
Analyses of the Healthcare Commission audit
A series of analyses were carried out to look at the relationship between
previously identified causal factors and implementation as
measured by the Healthcare Commission audit of implementation of the
schizophrenia guideline.
Descriptive results
Items within the audit were collapsed into a number of key markers showing
adherence levels (Table 1).

Inferential results
In order to look at statistical relationships, the individual scores for
the audit were combined to give an overall proxy measure for implementation.
Correlations showed that better levels of implementation were associated with
the following factors (data at trust level):
The data were submitted to a step-wise linear regression. All variables from the NCCMH survey were input as independent variables, the schizophrenia proxy as the dependent. The model yielded a reasonable R2adj of 0.284 using three variables, model ANOVA significant (F=8.410, d.f.=3, P < 0.001), and collinearity statistics were within acceptable range (condition index=7.72). Variable (β) weights showing direction and strength of effect in the model were:
This interaction between commissioner support and corporate support has a powerful predictive effect on implementation.

NICE guidance implementation and key implementation indicators
The NICE principles of implementation (Box 1) are not being closely
followed by many trusts. It is encouraging, however, that a majority of trusts
seem to have some identified prerequisites for implementation in place,
showing engagement with guideline implementation, although it is arguable that
these might be seen as prerequisites for an effective clinical service, and
that their existence owes more to this than any link to guideline
implementation.
Markers from the schizophrenia audit
Some of the markers show high levels of adherence (use of depot medication,
documentation of response and side-effects in care plan, avoidance of
polypharmacy), whereas others are poorly adhered to (notably provision of CBT
and family interventions). The high levels of adherence on the top five
markers may be due to coincidence with established best practice rather than
to change driven by guidance. The low levels of CBT and family interventions
are possibly due to lack of availability and funding rather than commitment
from clinical teams to implementation.
Key findings
Hypothesis testing shows a clear link between corporate commitment and
leadership and implementation of guidelines. Corporate commitment is linked to
many key implementation markers - where it is lacking, implementation will not
be very far advanced. This hypothesis is clearly supported by the secondary
analyses of the Healthcare Commission data on NICE schizophrenia guideline
implementation. There is a clear link between corporate commitment and
leadership and implementation of this specific guideline, from both the
correlation and the regression analyses, the latter showing the interactive
effect of commissioner support and commitment and leadership (lack of
commissioner support is linked to poorer corporate commitment and
leadership).
It is interesting to note that a higher level of audit of health technology appraisals is linked to poor commissioning support and funding problems. This may be a function of two possibly unrelated effects: it may be that commissioners are insisting that an audit of an appraisal is undertaken as a prerequisite of funding being allocated; it is also possible that this audit is being conducted as a lobbying activity to persuade commissioners to allocate funding (via a demonstration of need).
Implications
This study shows empirically that in order for implementation to succeed,
the trusts board and senior managers must be engaged. Further, it shows
that commissioners must demonstrate support. These findings give ammunition to
trusts and to NICE to enable pressure to be put on commissioners in order to
improve support of NICE guidance and of its implementation. Further, these
data show that some trusts have advanced well in implementing guidelines,
providing identifiable best-practice models for others to follow.
